Research progress on rice blast fungus

The present article summarizes the identification and nomenclature of physiological races,infection mechanism,causes of variation and status of researches on gene of rice blast fungus.The lack of researches on the problems existed in species identification,infection mechanism and identification and application of avirulence genes for rice blast fungus have been discussed.Some strategies have been suggested,such as cultivating identification species of rice blast fungus used unified in international,enhancing some other infection ways of rice blast fungus for above ground parts of rice seedlings,and the research of avirulence genes of rice blast fungus,etc.,in order to deepen and speed up the research of rice blast fungus.
